Final answer:
Teece, a character from Ray Bradbury's 'The Other Foot', is likely to continue displaying racism after the Blacks leave Earth but may be forced to adapt to new societal norms.
Step-by-step explanation:
The question about how Teece would act after the Blacks leave Earth seems to reference Ray Bradbury's short story 'The Other Foot' from the science fiction anthology 'The Illustrated Man'. In this story, Teece is a character who displays racism and is unsettled by the prospect of black people returning to Earth after having colonized Mars. Knowing Teece's character from the text, it is likely that he would continue to exhibit racist attitudes and may attempt to resist the changes taking place. However, the story also suggests that Teece realizes his power is waning and he may ultimately be forced to confront his prejudices and adapt to the new societal norms that will arise following this significant cultural shift.
